Add a text watermark to every page of a PDF.
or drag and drop · max 50 MB
Stamp a custom watermark — like 'CONFIDENTIAL', 'DRAFT', or your name — across every page of a PDF. Control the text, color, opacity, rotation, and position. The watermark is rendered in your browser and baked into the output file, with no upload to a server. Common uses: marking drafts, confidential documents, or claiming authorship of shared materials.
